Note: these are estimates, and your own maximum heart rate might be quite different
(up to 15-20 beats per minute) from these predictions. If possible, and subject to medical advice,
you should conduct a maximum heart rate stress test to find out your own maximum heart rate –
see the FAQ for more information.

If you use one of these to predict your maximum heart rate then the last equation, estimated by
Miller et al from Indiana University, is likely to be the least inaccurate.
